7' Claims. (01. 204-248) This invention relates to an electrolytic water correction device and to a method of making the same. More particularly, the invention relates to an electrolytic Water correction device comprising a core of negative metal, such as zinc, and a coiled wire sheath therefor formed of a positive metal, or coated with a positive metal, and completely enclosing the core while permitting access to the core of the water in which the device is intended to be submerged.

In accordance with the principles of my present invention, a solid core, preferably cylindrical in shape, forms the negative element, and a multipart coiled wire sheath forms the positive element. The sheath is formed in two identical sections, each having cylindrical portions of helically coiled wire for threading one upon the other to enclose the cylindrical core, and having reduced end portions terminating in hooks for suspending the device or for attachment to similar devices in multiple. An end from one of the cylindrical portions is bent inwardly for engagement with the suspending hook of the other cylindrical portion so as to prevent separation accidentally or the two sections.

One of the advantages of this construction is that the resiliency of the coiled sections allows for expansion of the core metal, which takes place during its disintegration, while at the same time preventing the dislodgment of any substantial chunk of the core from within the enclosing sheath. As the metal of the core is used up, the coiled wire sheath continues to tightly engage the core and provide good electrical contact therewith for the set-ting up of galvanic action.

It is therefore an important object of this invention to provide an electrolytic water correction device in which the core is accommodatingly sheathed in a multi-part cage formed of helical- 1y coiled wire, the resiliency of which compensates for expansion or contraction of the core during use.

It is a further important object of this invention to provide a coiled metal sheath made in two parts, which are capable of being threaded one upon the other to provide a complete enclosure for a cartridge of a metal that is electro-negative to the metal of which the sheath is formed.

It is a still further important object of this invention to provide a coiled wire sheath for a negative metal cartridge of such construction as to be readily assembled in place and held against accidental separation, while at the same time providing for the multiple linking of other similar devices therewith.

It is a further important object of this invention to provide a method of making an electrolytic water correction device in accordance with which identical sections of coiled wire enclosures are provided with open ended cylindrical portions for threading one upon the other to enclose a core of negative metal with good electrical contact therebetween and to provide interlocking means for preventing accidental separation of the sheath sections after assembly on the core.

Other and further important objects of this invention will be apparent from the disclosures in the specification and on the accompanying drawings.

On the drawings:

Figure 1 is an elevational view of a device embodying the principles of my invention, illustrating in a fragmentary way the union of a plurality of such devices.

Figure 2 is an end elevational view of the de- Vice.

Figure 3 is a sectional view taken substantially on the line IIIIII of Figure 1.

Figure 4 is a sectional view taken substantially on the line IV-IV of Figure 2 with the core in elevation.

Figure 5 is an elevational view illustrating the method of assembly of the multi-part coiled wire sheath.

As shown on the drawings:

The reference numeral It! indicates generally a device embodying the principles of my invention. Said device In comprises a cylindrical core, or cartridge, H, which may be a solid bar of zinc, or other negative metal. A sheath, indicated generally by the reference numeral I2 is mounted upon said bar I I and encloses the same.

Said sheath l2 comprises two sections [2a and 12b, which are in every respect identical. Each of said sections 12a and P217 is formed of a plurality of turns of helically-coiled Wire of circular cross section and comprises a cylindrical portion [3a and I312, respectively, and a reduced diame- .ter end portion Ma and Mb, respectively. The

reduced diameter end portions terminate in hooks l5a and I512, respectively. As illustrated in Figure 1, a hooked end l5a may be engaged with the hooked end I of another similar device where it is desirable to position the devices in multiple.

The open end of each of the cylindrical portions l'3a and l3b terminates in an inwardly bent length of wire I6a or IE1) which may be bent around the adjacent hook I5b or 15a, as at 11a and I'll), respectively. In this way the two sections are prevented from being accidentally separated.

As illustrated in Figure 5, the core H is first inserted into the open cylindrical end of one of the sheath sections, such as the sheath section I 2a. At this stage, the end length of wire lfia extends laterally from the cylindrical portion lta. The cylindrical-portion I372 of the other section is then threaded over the cylindrical portion I31; by a relative turning movement, the outwardly extending end portion [619 in no way interfering with this threading operation. After the cylindrical portion l 3b has been completely.threaded-upon the cylindrical portion I3a, the end portions i621- and I'Bb are bent inwardly to engage the hook ends Ho and [lb about the hook ends [52) and I511, respectively, thereby interlocking the two section-s and preventing their accidental separar tion. The cartridge or core II is now completely enclosedwithin the assembled sheath I 2 and is ready for use;

Owing to the resiliency-of'the helical coil of the cylindrical portions, 13a and I31), the cylindrical core H" is at all times tightly engaged by and enclosed Withinthe sheath l2, despite such expansion or contraction as may'take place during the use of the device in the heated water of a boiler, or, the like. maintained between the sheath and the cartridge at allttimes, insuring an efiective galvanic action for the dissolution of' the negative metal of the cartridge; Thisaction is explainedin my issued PatentsNos. 2,321,796; 2,321,797 and-2,348,882.

The term positive as used herein designates metals positioned below hydrogen in the electromotive force; series of metals. The term negative asused herein designates metals positioned above hydrogen in the electromotiveforce series of metals.

' It will; of course, be understood that various details of construction may be varied through a wide range without departing'from the principles of, this invention and it is, therefore, not the purpose toJimit'the patentgrantedhereon otherwise than' necessitated by the scope of the appended claims. g
